The paper describes the sensitivity analysis carried out in the computational evaluation of wind effects on buildings by using a computer code named TWIST - Turbulent WInd Simulation Techniques. The code includes two simple modifications on the standard k-ɜ turbulence model and a new zonal boundary treatment method for the turbulence variables. The sensitivity analysis addresses the size of computational domain, the number of grid nodes and the criteria for terminating the iteration process.
